Pulsed-Laser Atom-Probe Studies of Surface Chemical Reactions

摘要

The pulsed-laser and imaging atom-probe are emerging as powerful tools for the study of surface chemical reactions. Detailed studies of molecular processes such as thermal dissociation provide valuable insight into the basic interactions governing a reaction sequence, and extended studies should lead to a complete understanding of simple surface reactions such as CO oxidation, methanation, etc. The combination of these techniques with a high-pressure reactor add a new dimension to the study of surface reactions, and, as the CO oxidation investigation reported here demonstrates, information with direct applicability to commercially important catalytic reactions can be obtained.
